Remarks

The DataProvider class provides basic information about a DDEX provider and methods for querying about or creating provider-implemented objects. This class is the bootstrapper for all DDEX provider-specific entities.

DDEX provides the single implementation of this class. This implementation is based on information read from the registry, and as such does not require that code implementing the provider be loaded.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
